COMP CAM experts ID HELP
I have a Comp Cam from Katech racing back in 2002 and I am trying to verify the specs to figure out what Comp cam this is.
This was part of the Corvette Stage II head and cam package I got from Katech in 2002 and the contact person no longer works at Katech.
The data sheet:
Part name: CLS1
Grind #: 3722/3724
Serial#: X 2533
report#: 6299
LSA: 114.00
Intake Duration crank degrees @.050: 223.9 (224)
Exhaust Duration crank degrees @.050: 227.9 (228)
Intake max lift: .3420 (???????)
Exhaust max lift: 3460 (??????)
I am not sure how to read the lift correctly! How do I determine absolute lift? Is this a .581/.588 lift cam? Would this cam be ok for a blower?
Thanks in advance

PS: I found a cam at Comp with similar specs: 54-444-11 / XER273HR
Hydraulic Roller-High RPM Street Strip with XE-R lobe designs.These are the most aggressive lobes for all out applications.
RPM-Range: 2000-7000

Yes. It's a 581/588 lift cam. A highly respected engine builder told me that he doesn't like the XER lobes because the ramp speeds are too fast and cause loss of valve control. I prefer more exhaust duration than what you have, but you'll be fine with that cam.
